Fuck people who left and hurt me

I am venting here and just getting my thoughts out here. People can be so mean to kind genuine caring people. It hurts. Yes it does. But it makes me stronger in some way. I think it makes me stronger by realizing I dont need them. In the end I need myself and only myself. Were all gonna die alone anyway so I might as live a life that's full of greatness for myself rather than crying for people who hurt and betrayed me. In the end, I am becoming a new me and it still hurts badly at times, but I know there's greatness for me that I can't see.
